120 x 90 x 180 cm · 1.08 m² · PAR+ fabric · Ø22 mm frame · 75 kg load · 2-year warranty
The 120 x 90 cm footprint is the sweet spot for cultivating 3 to 6 plants in 11-15 L pots without filling up your room. The Homebox Ambient R120 sold by BloomLED combines 1.08 m² of usable surface, an ultra-reflective PAR+ inner fabric and a reinforced frame strong enough to hang your LED grow light, your inline fan and your carbon filter — all inside a tent built to last several cycles without visible wear.

Unlike square 120x120 tents, the R120 slides along a wall, into a closet or under a sloped ceiling. Its 90 cm depth keeps walkways clear while still delivering 1.08 m² of canopy area — enough room for 4 plants in 15 L pots in a relaxed setup, or up to 6 plants in SOG. The surface-to-footprint ratio is one of the best on the market for urban indoor growers.
The inner lining uses HOMEbox's signature PAR+ coating: a matte, diffuse-reflective surface that bounces back up to 95 % of photons without creating hot spots. In practice, your LED works less hard to deliver the same DLI at the canopy — a real PPFD gain and meaningful energy savings over the cycle, especially during flowering.
The R120 ships with several Ø 100 to 200 mm intake and exhaust ports plus reinforced cable sleeves. You can mount an inline Ø 125 mm fan with a carbon filter inside, add passive or active intakes near the floor, and dial in your VPD precisely. Vents and pass-throughs are positioned to prevent any odour back-flow.
The 22 mm epoxy tubes and steel connectors support up to 75 kg — plenty of headroom for a 300-480 W LED, an exhaust kit and a carbon filter combined. Assembly takes under 30 minutes, alone, thanks to click-in connectors: no screws, no tools, and a fast tear-down for relocating or switching configurations between cycles.
All seams are double-stitched and the zippers are calibrated to block any stray light — essential to protect a strict 12/12 photoperiod during flowering. The waterproof tray on the floor catches watering splashes: a small detail that makes a real difference in a flat or a finished basement.
HOMEbox is the historical German reference for indoor grow tents, distributed by Eastside Impex for over 20 years. At BloomLED — a France-based growshop with 10+ years of expertise — your order ships within 24 working hours with tracking and bilingual technical support: matched LED light recommendations, ventilation kits, simplified returns.
For 1.08 m², plan on 300 to 480 W of high-quality LED to reach an average PPFD of 800-1100 µmol/m²/s in flowering. A 320 W fixture with a Meanwell driver and Samsung LM301B/H diodes covers the R120 comfortably from veg to bloom. BloomLED offers turnkey kits sized specifically for this tent format.
Which inline fan should I pair with the R120?Usable volume is roughly 1.94 m³. For one air exchange every 1 to 2 minutes (recommended in flower), a Ø 125 mm fan rated 280-360 m³/h paired with a matching carbon filter is ideal. Add a thermostat or speed controller to lock in 24-27 °C and 50-65 % RH depending on the growth stage.
How many plants fit in 1.08 m²?In organic soil with 15 L pots, 4 plants left to grow naturally fill the R120 nicely. In SOG (Sea of Green) with 7-11 L pots, you can run 6 to 9 plants for shorter cycles. In SCROG, 2 to 3 plants trained on a screen exploit the entire lit canopy. The choice depends on your yield goal and patience.
Is 180 cm tall enough?Yes for 90 % of indoor setups. You leave about 30-40 cm for the light and exhaust at the top, 25-30 cm for the pot and saucer at the bottom, leaving 110-125 cm of usable plant height — plenty for indica or hybrid strains that you train, or for sativas under SCROG. Untamed sativas may prefer the 200 cm variant.
How well does the PAR+ fabric age?The PAR+ coating is designed to withstand UV, humidity and temperature swings for over 5 years of continuous use. A quick wipe with warm water between cycles preserves the reflectivity. The 2-year HOMEbox warranty covers manufacturing defects, handled at no charge through BloomLED's customer service.
BloomLED tip: the R120 is the perfect tent to step up from an 80x80 to a real production-grade setup without taking over your living space. Paired with a 320-400 W LED from our catalogue and a Ø125 ventilation kit, it delivers 3 to 4 cycles per year with comfortable headroom.
